About our remedial sealant in Sandon
A joint that keeps letting you down needs more than another bead. Send pictures when you call 0345 464 0079 or drop us an email, and say how long ago it was last done. Common call-outs are for floor or wall movement joints that have failed and smears and lumps from a botched reseal, across leaking tray & enclosure joints, shrunken worktop sealant and mouldy bath & shower sealant.
In a village or hamlet like Sandon, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

When something else is needed
In fairness, there are a few things sealant will not fix:
- Older mastics that may need an asbestos check before removal
- Failed tanking or loose tiles behind the sealant
- Cracks in the fitting rather than the joint
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

What happens if it’s left?
Ripping out a bathroom is not usually needed. If the bath, tray and tiles are sound, remedial resealing normally puts it right. Where something else has failed, you will hear it from us. Older cottages and farmhouses around Sandon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Keeping the joints in good condition
So the new joints stay in good condition:
- Act on a lifting corner straight away
- Always have old sealant cut out, not covered
- Report a tray that rocks or a worktop that lifts
- Use a soft cloth, not a scourer, on silicone
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
Don’t keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
Sandon homes and their sealant
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Ashwell & Morden station, botched sealant from a previous quick fix is easier to strip out between tenants. For an older house near a landmark such as Church of All Saints, walls and floors in older homes can move, and sealant and grout show it first. For site and facilities teams at buildings such as Sandon Junior Mixed and Infant School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What happens on the day
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a typical bath or shower, longer where several layers have been applied from start to finish. Somewhere as small as Sandon, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts

Advice
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

How the job changes by surface
Mouldy bath & shower sealant
Repeat mould generally points to a damp, poorly aired room. Along with resealing, we will mention if the room needs better ventilation.
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
